My experience is that Speak and TamTam work, but Record, Scratch, and eToys
do not.

I suspect this is either an interface approach or a sampling rate issue.
If I try to sample at the wrong rates with arecord & aplay I get no audio
back at all.  Attempting to change the dmix rate from 44.1 kHz to 48 kHz
does not solve the problem.

On XO-1.75 I believe we resorted to software resampling; I do not know if
this is in place for XO-4 or not.

Something also seems to be writing over the Mic Gain state as I found it at
zero once although it was about a third of the way up when checked earlier
in the same boot cycle.  Personally I like bumping it up pretty high.
